BJT gain should be . . . . . . . . to avoid latch-up effect. A. Increased B. Decreased C. Should be maintained constant D. Changed randomly

The correct answer is B. Decreased.

BJT gain is the ratio of the collector current to the base current. When the gain is high, a small change in the base current can cause a large change in the collector current. This can lead to latch-up, which is a condition where the transistor is turned on and cannot be turned off. To avoid latch-up, the gain of the transistor should be decreased.

Option A is incorrect because increasing the gain will increase the risk of latch-up.

Option C is incorrect because maintaining the gain constant will not prevent latch-up.

Option D is incorrect because changing the gain randomly
